Letters Patent No. 98,548, dated January 4, 1870.

IMPRovED WEATHER-STRIP.

The Schedule referred to in these Letters .Patent and making part of thesama To all whom it may concern Be it known that we, JAMES T. BLISS andJOSEPH D. DAVENPORT, both of North Providence, in the county ofProvidence, and State of Rhode Island, have invented a new and usefulDoor-Attachment for a substitute for thresholds; and we do herebydeclarethat the following specification, taken in connection with the drawings,making a part of the same, is a full, clear, and exact descriptionthereof.

Figures 1 and 2 are sectional views of so much of a l door and the jambas will, show the attachment, the

door in tig. l being represented as ajar, and in fig. 2 as closed.

Figure 3 is a front view of' the door and the attachment.

The only function which thresholds to interior door-v l carpet.

` A carpet, if the door isintended to be used, cannot be laid over thecommon raised threshold, as it is often desirable to do in order toimprove the effect ot' two connecting rooms, which are covered with acarpet ot" the same pattern, and architects have long desired to devisesome means which would dispense with the tlires'hoid,andyetprevent adraught-space nnderfthe door.

Our invention accomplishes this enchand consists in the attachment of ahinged plate to the bottoni; rail of the door, which, by the action of aspring, is lmade to lie a't. against the edge of the bottom rail whenthe door is open, but will be turned down so as to close the spacebetween the bottom rail and the floor when .the door is closed.

Although the idea is borrowed from the well-known spring weather-stripsused upon outside doors, and

operates in a somewhat similar' way, it is nevertheless' to bedistinguished from that device iu its arrangement and adaptation to thepurpose intended.

lIn the drawings- A s the door;

B, the door-jamb; and

C, the floor, which may be carpeted or not, but if intended to hecarpeted, allowance in hanging the door should properly be madetherefor.

As seen in the different figures, the door' is hung so as to clear thecarpet or ioor entirely when swinging. A plate of thin metal, or othersuitable material, D, is hinged, at a, to the' edge of the bottom rail,and it is preferred, for appearance, to make a rebate in such hinge.

Upon the edge ofeachstile of. the door an opening is cut, which shouldbe closed by a neatly-ittingplate capable of removal, if necessary.

At each extremity of the iiap D, and at right angles therewith, ornearly so, are arms E, against which -a spring, I1, is made to bear.Both spring and arms are concealed by the covering plate abovementioned.

In each Aangle of the common rebate inthe doorframe, an invertedinclined plane, G, is set. l Thel eiect is apparent. Upon closing thedoor-,the front edge ofthe tlap D will strike the planes G, and," inconsequence, such yplate will be turned down, and close the spacebetween the bottom of the rail and the carpet, and much more ei'ectnallyexclude cold l currents of air than the ordinary threshold would do.

Upon opening the door, the action of the springs F will fold the tlap Dagainst the bottom o the rail.

XVe do not claim, broadly, a hinged flap, in combination with a door anda stop or inclined plane upon the jamb, to close the crack between thedoor and the threshold; l neither do we broadly claim the use of thespring F, arranged to operate directly upon the hinged plated) but Vt'eclaim, and `desire to secure by Letters Patent-` The substitute forthresholds herein described, consisting ot' the combination of thehorizontal hinged plate D with the arms E E, controlled by the spring F,and operated by the plane G, construct-ed, arranged, and operatingsubstantially as described.
